It is hard to tell if your pricing is correct, as there are so many factors involved. It sounds like you are asking for a turnkey job where you write a check at the end and someone comes in and removes, prepares and constructs you a new driveway. Location, soil conditions and on and on will factor in. There are also unknowns and how bad the guy quoting needs the job.
Many years ago my mother had a small one car pole barn built and I advised her to hold back some of the money until it was fully done. It got to the end and she still owed him 500 bucks and all he had to do was rake the yard for scraps of tin and paint the man door. After a couple weeks I called him and asked when he was coming to finish the little bit of work. He told me if I would keep the money he was ok with it. I spent 10 minutes raking and 20 minutes painting her door and she got to keep her 500. The guy was so busy he couldn’t find an hour of his time to make $500.
Many times people make sure it is worth it for them when doing a quote and other times they have a crew they need to keep employed and will take a job rather than lay them off.
IMO I would never do an asphalt driveway in any of the northern states unless it was really a lot less money and knowing it will require yearly work done to it and even then wont hold up long term. If I wanted to go cheap and could find someone that still does it and I had a good gravel base I would look at tar and chips.
